一个带有加载动画与数据为空时显示EmptyView的ListView，用FrameLayout与ListView实现。
##使用方法
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
elv = new EmptyListVisew(this);
lv = elv.getListView();
elv.setProgressView("正在加载中...");
setContentView(elv);
post();
}
int i = 0;
void post() {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
if (i == 2) {
lv.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, new String[]{"hello", "world"}));
}
elv.setEmptyView(R.mipmap.ic_launcher, "加载失败,点击刷新", new View.OnClickListener() {
@Override
public void onClick(View arg0) {
elv.setProgressView("继续加载...");
i++;
post();
}
});
}
}, 2000);
}
